Bench marking Server/Data Centre

Hi

I am exploring the ways to measure server capacity/benchmark.

I am planing to use TPC-C.(tpmC-Transactions per Minute) as most of our servers have database(OLTP) transactions. If I want to bench mark whole of the datacentre(set of servers) how should I do so? Can I add this(tpmC) values for all the servers? Or is there any better way to do that?

Please advice.
Thanks

Re: Bench marking Server/Data Centre

Jeya, are you benchmarking your servers to determine how your configurations stack up against published TPC-C's? We use glance/measureware and perfview to collect and report our performance statistics. The problem I have with any kind of standardized "performance testing" programs is that they never capture how the real world behaves, especially when you have a group of servers that work together to solve problems. I'm not sure if I helped you at all, but I wish you good luck!

Harry,Thanks so much for your reply.
I wonder whether I conveyed my question correctly. My problem is I need to quantify the server capacity. I am planning to use tpmC (TPC-C). So if there are so many servers what can I do so? Can I add up all the tpmC values? Or is there any other better way to this?

Thanks so much.

Re: Bench marking Server/Data Centre

Jeya, that's a tough one because of the interdependencies. I would guess you could use each servers tpmC numbers individually, but I don't think you could sum them together and get a fair representation of how many transactions you can process in a certain time period unless a group of servers are performing the same task - like a cluster of application servers servicing a single application.

I would look at it from an application view and determine which servers belong to that group and maybe use the tpmC numbers (for just that group) as a whole.

Capacity planning is an art, because you have to know when to generalize and when to be specific.

Re: Bench marking Server/Data Centre

Harry,many thanks.
As you mentioned,I wonder whether just adding up of TPC-C figures will work. My aim is to compare the server capacities before and after we purchased a new set of servers. I wonder whether are there any other better ways to do this? Most of our servers are used as OLTP servers.Any ideas?
